Patented Nov. 22, 1949 2,489,192 ROTATING SPRINKLER FORrLA WNS Franci L McGuig hl fidlandils Application July 15, 1947, Serial No. =760',9'71 lflla ms- -2333a! This invention -relates to a s rinkle an is, more particularlyrcumernedwith a lawn sprayer or sprinkler of the character wherein a liquid fertilizer, insecticide or other chemical is sprayed over a lawn .inadmixture with aspray of water delivered through a hose or similarconduit.

A primary object of the invention is to provide a lawn sprayer wherein a liquid fertilizer or chemical is fed by gravity into a depression ,in

the ltop of .a rotary spray head, and the spray head isprovided externally thereof withhelically arranged ribs partially overhanging perforations through which jets of water from a hoseor the like areldirected for rotating the head, .the head being formed to provide forroutward movement of the liquid fertilizer by centrifugal action and in admixture with the water from the jets, whereby a relatively large fiertilizer bearing spray is directed laterally of the axis of the rotary spray head.

A further object of the invention is the provision of a lawn sprayer of this type which, while being relatively simple in construction, is highly efficient in operation Other objects and advantages of the invention will become apparent in the course of the following detailed description, taken in connection with the accompanying drawing, wherein-- Figure 1 is a side elevational view of the improved sprinkler or sprayer in accordance with a preferred structural embodiment thereof.

Figure 2 is a horizontal sectional view as observed in the plane of line 2-2 on Figure 1.

Figure 3 is a horizontal sectional view as observed in the planes of the broken line 3-3 on Figure 1.

Referring now in detail to the drawing, the improved sprinkler comprises a base H! which is of substantial horizontal area and which is adapted for resting on the ground in different selected locations in the use of the sprinkler.

The base In is provided with a hose connection II which provides an inlet to an otherwise closed chamber [2.

The chamber l2 includes a cylindrical side wall and a plane circular top wall which is provided with a circular series of perforations l3.

A rod l4 includes a lower vertically disposed straight portion l4 whose terminal is suitably secured to the top wall of chamber [2, which portion provides a pivotal axis for a rotary spray head I6, the axis being concentric with the circular series of perforations IS.

The rod I4 is bent laterally of said axis above the spray head and is then provided with a horizgatall -zd.i p sed circular bottleesuppor-tinz ring .Elhe renter shead 416 is for generally inverted f u t ccnical dorm with the, side wall the eof curving inwardly toward' i'ts axis ofvrzpliatiop, and the -.unn rand la er and of the .headeve han the perf ra ions 1:3 as is rcl arly ind ca ed i f s ell- V The hea 4 srm idedw th e cally-di osed r bam ene l ormt tien oft eihead by imngement o jets 9 water 17' a a nst :t e edge walls thereof, which jets issue from the tion 13, as i ind ca ed in :E eure al- T he d 16 cludes an :inn r hu' at the ra r n hereof and depression I9 is provided in he uppe he head in surroundi g relation t th hu The riquid fertilizer o chemi i c ta ed within abet-tie wh h, in use-isinv ted .nd is supported adjacen it h ad a t e .lFiRg lfil asiisi dica edinFi ural,

A fertilizer-delivery nozzle 20 extends through the cork c in the bottle B into communication with the interior of the bottle, and the outer end of the nozzle is disposed within the depression IS. The upper edge of the side wall of the head I8 is provided with radial grooves 2| intermediate the ribs 11 for a purpose later to appear.

In the use and operation of the improved sprinkler as above described, the base I0 is placed at any desired point on a lawn and a hose connected with the inlet H of the chamber I 2.

The bottle B containing the liquid fertilizer or chemical is then placed in inverted position and supported by the rin IS, with the lower end of nozzle 20 disposed within the depression I9. The water is then turned on with resulting pressure jets a acting on the spiral ribs l1, thereby effecting rotation of the spray head IS.

The liquid fertilizer or chemical will be fed by gravity into the depression l9 and will be expelled through the grooves 2| by centrifugal force. The water from jets 7' will travel upwardly between the ribs l1 and, due to the outer flare of the head, such Water will admix with the liquid fertilizer, whereby a substantially horizontal sheet spray will result.

After spraying any one area, the device may readily be transported for spraying an adjacent area.

It is to be particularly observed that the improved device is relatively simple in construction, durable, and at the same time highly effective in operation.

While I have disclosed my invention in accordance with a single specific embodiment thereof, such is to be considered as illustrative only,

and not restrictive, the scope of the invention being defined in the following claims.

What I claim and desire to secure by U. S. Letters Patent is:

1. A fertilizing lawn sprayer comprising a base having a water chamber associated therewith and a hose connection communicatingwith the chamber, said chamber having a horizontal top wall, a rod including a'vertical portion secured in said top wall, an elongated head rotatably sup-.

ported above said chamber on said vertical por tion of the rod, a circular series of perforations.

in the upper wall of said chamber in surrounding relation to said rod portion for formation of vertical water jets therefrom,said head having an upwardly diverging outer wall concentric with an inverted liquid fertilizer-containing bottle in said vertical rod portion and provided with spiral 1y disposed ribs for rotation of the head by impingement of the jets on the ribs, a depression in the upper end of the head in surrounding relation to said rod portion, and means supported by said rod for delivering liquid fertilizer by gravity into said depression.

2. The structure according to claim 1, wherein a ring is provided on the upper end of said rod, and wherein said means comprises a liquid fertilizer container removably seated in said ring, and a liquid-delivering nozzle extending from the container and communicating with said depression.

3. The structure of claim 1, wherein the upper edge of said outer wall surrounding said depression is provided with radially disposed grooves between said ribs.

4. A fertilizing lawn sprayer comprising a base having a water chamber for connection with a hose and having an upper horizontal wall, a rod having one end'thereof secured to the upper wall of said chamber, a portion of said rod being inverted position, a depression in the upper end of said head in surrounding relation to said vertically disposed rod portion, and a liquid delivering nozzle communicating with the interior of said bottle and with said depression.

5. The structure according to claim 3, wherein said head. at the upperv end thereof is provided with radially disposed grooves between said ribs and between said outer wall and said depression.
